Title: Fluidic control apparatus
Inventor: HALES KENNETH CALVERT
IPC: F25D29/00
Filed: 1969-10-27
Abstract: 1298558 Fluid logic and switching circuits SHIPOWNERS REFRIGERATED CARGO RESEARCH ASSOCIATION 27 Oct 1970 [27 Oct 1969] 52548/69 Heading F1P [Also in Division F4] A valve X Fig.5 suitable for controlling flow of liquid nitrogen from a storage tank (T) Fig.4 (not shown) to a sprog header (H) inside a refrigerated cargo container (C) is open or closed according to the presence or not in a line 23 of a fluidic signal at an output O 1  of a NOR gate N 1  and the predetermined interval between the opening and closing of valve X is automatically determined by a delay means in a closed loop in which a second output O 2  of gate N 1  is connected to a control input A of N 1  by means of capacities V 1 , V 2 , V 3  NOR gates N 3 , N 3  an open valve 51 and a line 25 having a branch 29 in which when the start button is pressed exists a constant pressure signal generated by a known flip-flop comprising cross-connected NOR gates N 8 , N 9 . A suitable NOR gate comprises a closed coil spring 11 Fig.2 connected at one end to a diaphragm 15 subjected to control input pressures at A, B and connected at the other end with a power supply conduit 20 having a restriction 19 and a branch duct 22 in which an output does not exist when a control input signal is present at A, or B and which deflects the coil spring and so vents the power supply at V. The time delay may be extended by including in the loop further pairs of NOR gates N 4 , N 5  and N 6 , N 7  with capacities V 4 , V 5  and V 6 , V 7 ; valves 51, 52 being closed and 52,54 open. In operation and with valve 51 open and valves 52,53,54 closed and supply pressure off, capacities V 1 , V 2 , V 3  are initially at atmospheric pressure with supply pressure on, a signal exists at O 1  and hence at 23 to open valve X and on pressing the start button the resulting pressure in lines 29,25 charge the capacity V 3  to a pressure sufficient to provide a signal at the control input A of gate N 1 , the input B of which is blanked off. The output at O 1  is thus zero and valve X closes. The output at O 2  of N 1  is also zero as is the control input B of N 2  whereby the output of N 2  charges the capacity V 2  to provide an input to N 3 . The output of N 3  is thus zero and capacity V 3  is vented resulting in the input at A of N 1  being zero and there being an output at O 1  of N 1  which again opens valve X 1 . The cycle then recommences. In a modification the circuit includes a pair of closed loops (31', 37') Fig.7 (not shown) each provided with a NOR gate and a delay system in series.

IPC: F16K31/18
Filed: 1967-11-24
Abstract: 1,216,087. Jet pumps. RAINBOW VALVE CO Ltd. Nov.22, 1968 [Nov.24, 1967], No.53653/67. Heading F1E. [Also in Divisions B1 and F2] A float-controlled valve, particularly for controlling the mixing of an additive liquid 9 with a bulk liquid in a tank 1 used for livestock drinking water, comprises a float 21 on the end of an arm 18 pivoted at 20 and having a finger 26 which engages a spring -biased operating member 12 of a conventional valve when the lever 18 moves downwards from the valve closed position to the valve open position. The lever 18 is pivotally connected to a lever 22 which is adjustably biased by a spring 24 so that a roller 23 engages in one of two grooves 17 1 , 17 2  to latch the arm 18 in either valve open or valve closed position, to arm 18 moving rapidly to the other position when the liquid level has altered from L 1  to L 2  or vice versa. Full flow through the tank inlet 4 is thus always obtained and an ejector Fig.2 (not shown) mixes the additive in the required proportion, the flow from the reservoir 9 being controlled by an adjstable orifice 11 and a check valve 6 and passing through a filter 8 and a flow rate indicator 10. In a modification a supplementary float is pivotally connected to the float arm 18 and moves between stops thereon. Abutment of the supplementary float arm with a stop causes the arm 18 to rapidly move between valve open and closed positions. In a further modification the float is pivotally connected to the arm 18 to move between stops thereon, the float being biased to a position in line with the arm 18 by a zaring. In an alternative arrangement arm 18 operates electric switches for a valve actuating electromagnet.

Abstract: 1,212,365. Thawing frozen foods. SANYO ELECTRIC CO. Ltd. 8 Dec., 1967 [10 Dec., 1966], No. 56003/67 Heading A2D. [Also in Division H5] To ensure even heating of a body 14 during defrosting in a microwave oven 10, a cooling gas is circulated through the oven cavity 12 to cool the surface of the body and the microwave energy is progressively reduced during the defrosting operation.

A heat exchanger 31 in the passage 30 co-operates with a cooling unit 31<SP>1</SP> beneath the passage. The microwave energy may be continuous or intermittent during defrosting. If continuous the intensity to finally reduced, and if intermittent the time periods of successive pulses may be successively reduced, or the intensity of microwave pulses may be successively reduced.

Title: Mutable code converter
IPC: H03M7/00
Filed: 1966-12-19
Abstract: 1,172,508. Code converters. RANK XEROX Ltd. 19 Dec., 1966 [27 Dec., 1965], No. 56663/66. Heading G4H. A digital code converter for converting code groups into larger code groups uses a circulating memory loadable through logic means with conversion information. A code converter comprises a recirculating magneto-strictive delay line containing 84 segments each of 117 bits, preceded by a group of sync. bits. An input bit group representing one of 117 characters is compared with a counter specifying the bit position reached in the current segment of the delay line. On equality, which occurs once (at the same time) in each segment, the current delay line bit is gated out to a C.R.T. display. The delay line is preloaded, e.g. over telephone lines, from a computer (which can thus alter the font), which also supplies the character bit group to be converted. These two types of input are distinguished by a bit preceding them. Use in cryptography is also mentioned.

Abstract: 1,200,231. Polymerization of ethylene sulphide. ETHYLENE-PLASTIQUE S.A. 27 Nov., 1968 [14 Dec., 1967], No. 56849/67. Heading C3R. Ethylene sulphide (or mixtures thereof with homologues in which the hydrogen atoms are substituted by hydrocarbon radicals) is polymerized in a medium comprising dimethyl sulphoxide. The medium may be dimethyl sulphoxide alone or mixtures thereof with other aprotic solvents which may yield homogeneous or heterogeneous media, e.g. aliphatic or aromatic hydrocarbons, cyclic or non-cyclic ethers, N,N- dialkyl amides or nitriles; in the case of mixtures dimethyl sulphoxide may comprise at least 10% by volume of the polymerization medium.

Title: Improvements in or relating to inverter commutation circuits
Inventor: WILLIAMSON KEITH HAROLD
IPC: H02M1/06
Filed: 1968-11-27
Abstract: 1,242,539. Electric converting systems. MULLARD Ltd. 27 Nov., 1968 [15 Dec., 1967], No.57231/67. Heading H2F. In a commutation circuit for a static inverter 2 (not described), e.g. in battery electric vehicles, a thyristor Th 1  is first triggered by a control pulse so that capacitor C charges to the supply voltage, whereupon current through Th 1  ceases and it reverts to its blocking state. Subsequent triggering of a thyristor Th 2  allows current to flow to the inverter and causes the charge in C 2  to reverse by ringing of a choke L 2 , a diode D 1  then preventing discharge of C 2 . When Th 1  is again triggered the voltage across the capacitor is momentarily applied as a reverse voltage across the inverter because of the impedance of a current limiting choke L 1 . This reverse voltage aids the commutation action of the inverter and in addition causes Th 2  to turn off. After a period determined by the values of C and L 1 , C discharges completely and is then recharged to the supply voltage ready for the next commutation cycle. Overload protection of the inverter may be effected by removal of the source of trigger pulses from Th 2 . The inverter thyristors may be slowturn-off types leaving the turning-off action to Th 2 . Control of the direct voltage to the inverter can be effected by varying the delay time between triggering Th 1  and Th 2 .
